Question

Help me!!! Please to solve this problem of o. Math

Answer 1

a:-

f(x)=2x+3

$\\ \rm\Rrightarrow f(1)=2(1)+3=2+3=5$

$\\ \rm\Rrightarrow f(-5)=2(-5)+3=-10+3=-7$

$\\ \rm\Rrightarrow f(a)=2a+3$

$\\ \rm\Rrightarrow f(a+2)=2(a+2)+3=2a+4+3=2a+7$

$\\ \rm\Rrightarrow f(b)=2b+3$

b:-

f(x)=x+4

$\\ \rm\Rrightarrow f(-2)=(-2)+4=2$

$\\ \rm\Rrightarrow f(3)=3+4=7$

$\\ \rm\Rrightarrow f(7)=7+4=11$
